Hagerman Fossil Beds Visitor Center

Don’t miss visiting the Hagerman Visitor Center. It is the only place in the monument to see fossils.

The old Hagerman Fossil Beds Visitor Center in downtown Hagerman is closed as they move into a new facility. A new inter-agency Thousand Springs Visitor Center is opening soon.

A soft opening is scheduled for September 2021 with limited fossils on display. The full opening is planned for 2022 with a new park film, all-new educational fossil exhibits, park ranger programs and recreation information.

Drive to an Overlook

There are two scenic overlooks within the park, Snake River Overlook and Oregon Trail Overlook. Both sites offer picnic tables and vault toilets.

Snake River Overlook

The Snake River Overlook offers panoramic views of the Snake River. Wheelchairs and those with mobility limitations can visit the viewing platform along the short paved walkway.

The distant cliffs lining the opposite banks of the river are fossil-rich. Educational interpretative signs share details about Hagerman during the Pliocene era, 3 million years ago.

Oregon Trail Overlook

The Oregon Trail Overlook requires a short walk on an unpaved path. It also offers views of fossil-rich distant bluffs and the Oregon Trail. Educational interpretative signs along the path share details about the human history of the area. Expect to learn about the life of Shoshone natives, settlers who traveled the Oregon Trail, and scientists who work in the area now.

Hike the Emigrant Trail

Due to steep and unstable terrain at Hagerman Fossil Beds National Monument, hiking is restricted to established trails. The only hiking trail in the National Monument is the Emigrant Trail.

It is a 6 mile out and back. The hike can also be done in one direction if you have two cars or a non-hiker who can drive between the trailheads. Trailheads are located at the Oregon Trail Overlook and Snake River Overlook.

The trail runs parallel to the Oregon Trail. It offers visitors insight into the experience of early homesteaders.

If you are interested in more hiking near Hagerman, we recommend the Box Canyon trail at Thousand Springs State Park. For more details, check out Best Things to do in Twin Falls: Maximizing your trip to the Idaho Magic Valley

Attend a Ranger Program

Park Rangers offer educational programs at the Hagerman Fossil Bed Visitor Center. Topics include geology, fossils, history and more.

We love finding free National Park programs that coincide with our visit. They are a great way to build an understanding of the location and ask the questions that have been intriguing you during your visit. Check the park calendar for scheduled programs.

What is a fossil bed?

Fossils are the remains of living organisms that have been preserved in the Earth’s crust. Fossil beds are the locations where fossils have been discovered.

Each year over 3,000 new fossil fragments are found in Hagerman.

Paleontologists collect and study fossils to learn more about the Earth’s origins. Fossils can explain unique events such as drastically changing weather patterns. They also provide insight into the evolution of species over time. The proximity of fossil finds can explain the dependency of one species on a different seeming unrelated species during certain periods.

What fossils are found in Idaho?

Fossils are abundant in Idaho. Rich deposits at Hagerman Fossil Beds represent an entire paleontological ecosystem with a variety of habitats such as wetland, riparian, and grassland savanna.

The most famous fossils found in Hagerman Idaho belong to the single-toed Hagerman horse, Equus simplicidens. Over 200 specimens of the Hagerman horse have been discovered at a single site, called the quarry.

Several fossils were first found in Hagerman Idaho. These discoveries continue to add to our understanding of the Pliocene era.

Over 200 different species of fossil plants and animals have been discovered in Hagerman Idaho. A few of the partial fossils featured in the visitor center are sabertooth cat, mastodon, bear, camel, and giant ground slot.

Where can you dig for fossils in Idaho?

Due to rich fossil deposits, Hagerman Fossil Beds and several other areas in Idaho have been set aside as research areas. Personal digs are not allowed for fossils or rocks. Only authorized park staff are permitted to dig for fossils in Hagerman Idaho.

However, visitors are permitted to dig for fossils or rocks on some Bureau of Land Management public lands without a permit. Check land-use restrictions at the regional ranger station. Two-thirds of Idaho is designated as public lands.

Generally, collecting petrified wood and invertebrate fossils on public land is allowed for non-commercial use. The rough guideline is a modest amount of invertebrate fossils such as coral, snails, leaf plants and mollusks are allowed to be collected for personal use. Items collected cannot be sold for profit.

Hagerman Horse

The Hagerman horse is a small horse species, similar to a zebra, and predates the horses brought over by the Europeans. It is the state fossil of Idaho. You can get close to a full horse skeleton at the Hagerman Visitor Center.

A section of the fossil bed contained the remains of hundreds of the same species of horse. The reason why so many horses were killed at the same spot with no other species is not known but scientists have stopped digging the area and have moved to other nearby areas. Hagerman Horse fossils are on display in the Smithsonian museum and many other museums around the world.

Excerpt about the distribution of horse fossils to other institutions from a 2015 Smithsonian article.

“The Smithsonian had more horse fossils than it needed for research or exhibit at the time. They decided to trade with other museums that did not have horse fossils. Smithsonian archives contain letters detailing offers of, and requests for, fossil horse skeletons and skulls. The Colorado Museum of Natural History traded a skeleton of Equus simplicidens for a skeleton of the early rhinoceros Trigonias osborni around 1931, and a 1932 exchange with the Los Angeles County Museum of History, Science and Art was worth a Pleistocene horse, Equus occidentalis. In 1933, an exchange with the Royal Ontario Museum brought skulls of the Late Cretaceous dinosaurs Prosaurolophus maximus (USNM 12712) and Edmontosaurus regalis (USNM 12711) from Alberta in exchange for horse fossils. A complete fossil horse skeleton, eight skulls, and five months of Charles W. Gilmore’s time was deemed equal to a partial skeleton of the Late Jurassic dinosaur Camarasaurus from the Carnegie Museum of Natural History in Pittsburgh in 1935.”

Where did the Hagerman Horse live?

The Hagerman Horse was discovered in Hagerman Idaho. It was the first true horse with a single toe. However, its bones most closely resemble Grevy’s zebra. It is believed horses, such as the Hagerman Horse, thrived in North America until droughts caused their extinction.

Horse species in Asia and Europe survived the same period. They evolved over time into different species. European settlers to North America reintroduced horses to the area.

This video details the areas of the park including a section of the Horse Quarry dig site.

Where to stay in Hagerman

Hagerman is located in southern Idaho within 30 miles of Twin Falls. The City of Twin Fall offers national hotel brands. Below we provide several camping options in Hagerman near the fossil beds. Camping prices range from free dry camping to resort amenities and prices.

Hagerman Fossil Beds Camping

As full-time RV travelers finding an affordable campsite is challenging.

Hagerman Fossil Beds National Monument does not offer camping on park property. There is no park campground and dispersed camping is not allowed on park property. However, there are several campsites in the town of Hagerman or even more options in nearby Twin Falls.

Affordable camping near Hagerman: Twin Falls County Fairground

While visiting the Twin Falls and Hagerman area, we stayed at the Twin Falls County Fairgrounds.

If camping at the fairgrounds, the drive to Hagerman Fossil Beds is 30 miles. The campground offers hundreds of sites with water, sewer and electric hookups.

In 2020, we paid $106 for seven nights on a full hookup site. It is a great deal and we loved the location. However, the campsites have a few downsides. Sites are close together and all hookups are located at the back of the site. Connecting sewer requires multiple lengths of hose.

We took full advantage of the full hook-up life and took long showers, did laundry, did long cooks and ran the air conditioners without considering power consumption. The fairgrounds offer dry camping even cheaper. They even have a nice bathhouse available for campers’ use.

I’d recommend calling the Twin County Fairgrounds at 208.326.4396  to check current rates and confirm availability. RV sites are unavailable during large events such as the fair or livestock shows. We had to look really pitiful and basically beg for them to find room for us during a huge livestock show.

We loved staying at the Twin Falls County Fairgrounds. It is an attraction to visit in Twin Falls even if you’re not camping there. To read more about the fairgrounds and all of the things to see and do there, check out our Twin Falls post.
